Electrically conductive plastics

Work on electrically conductive plastics involves the development of chemical formulas and processes for manufacturing electrically conductive polymers, especially those that can be thermoplastical shaped. Modification with electrically conductive additives (e.g. carbon nanotubes, graphite, carbon fibres, carbon black, metallic fibres) or additive mixtures enable the production through extrusion techniques of composites with both antistatic (ESD) and highly conductive properties for the EMV sector.
The main applications include antistatic films for the packaging industry and housings for mobile phones, electronic devices, household appliances etc.

 

Selection of current activities

  • Reduction of filler content in electrically conductive composites by incorporation of multi-walled carbon nanotubes (MWCNT) and synergistic additive mixtures (e.g. MWCNT/steel fibres) into polypropylenes, polyester, ABS, PMMA
